American Medical Association (AMA) Style

AMA style is a format developed by the American Medical Association to standardize biomedical writing.  It is internationally recognized and used throughout disciplines in the health sciences. The library provides students and faculty complete access to the print and online editions of the AMA Manual of Style.  

Basic Rules and Principles
  • In-text Citations

In-text citations are used when a source is referred to in the body of a paper.  AMA uses a superscript number format.
